Winter Swimming Pool

Many public swimming pools are rectangles 25 m or 50 m long, but may be any size and shape desired. There are also elaborate pools with artificial waterfalls, fountains, splash pads, wave machines, varying depths of water, bridges, and island bars.
There are often lockers for clothing and other belongings. The lockers often require a coin to be inserted as deposit or payment. There are often showers ready for use - sometimes mandatory - before and/or after swimming. There are often also Lifeguards to protect the public.
Wading pools are shallow bodies of water intended for use by small children, usually in parks. Concrete wading pools come in many shapes, traditionally rectangle, square or circle. They are filled and drained daily due to lack of a filter system. Staff chlorinate the water to ensure health and safety standards.
